working.

Trying to run any program on AIX triggers a failed assertion:
(gdb) run
Starting program: /[...]/simple_main
/[...]/gdb_bfd.c:288: internal-error: gdb_bfd_unref: Assertion `gdata->refc >= 1' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
What happens is that we have a loop where we forgot to update
the value of "last", resulting in the loop unref'ing the same
BFD over and over again. We bomb the second time around, when
triggering an assertion on the ref counter.
gdb/ChangeLog:
* rs6000-nat.c (add_vmap): Set "last" to "next" after having
unref'ed it.

* target.c (simple_search_memory): Include access length in
warning message.

Moving some sparc-specific routines out of sol-thread.c into their
own (new) file.
gdb/ChangeLog:
* sol-thread.c (ps_lgetxregsize, ps_lgetxregs, ps_lsetxregs):
Move these functions to sparc-sol-thread.c.
* sparc-sol-thread.c: New file.
* configure.ac: Add sparc-sol-thread.o to CONFIG_OBS and
sparc-sol-thread.c to CONFIG_SRCS for sparc-solaris native
configurations.
* configure: Regenerate.
Add a declaration for procfs_find_LDT_entry in order to prevent
a compiler warning about this function missing one. This also
helps making sure that declaration and definition remain consistent.
gdb/ChangeLog:
* procfs.h (procfs_find_LDT_entry): Add declaration.
* sol-thread.c (ps_lgetLDT): Delete local declaration of
function procfs_find_LDT_entry.
This function is used as a target_ops callback. The function
implemention was recently changed, but the declaration wasn't
updated accordingly.
This fixes a build failure on Solaris.
gdb/ChangeLog:
* procfs.c (proc_find_memory_regions): Fix declaration.
